Lloyd makes an hourly wage of $9.50 per hour. Every 6 months he receives a $0.50 per hour raise. Write a rule that describes his raise and determine how much he will be paid after 4 years.
Let n be the number of 6-month periods he is employed
wage = 9.5 + 0.5n
after 4 years (8 periods) he will make
9.5 + .5(8) = 9.5 + 4 = 13.50
